In a new interview with Planet Rock, Lifeson offered more clarity on his own goals.

"I don't want to be in a band and tour anymore," he said. "I don't feel the need to carry on with what I did for almost half a century. I'm fine with it now. And I'm as busy as I would ever want to be."

But this marks the first time Lifeson has talked in explicit terms about his feelings on performing live again. He added in the Planet Rock interview that it took him about a year to "feel better" about retiring Rush.

"I realized we'd gone out on a high note," he said, before adding that he has beautiful memories of the final show.

Rush's 2015 retirement was mostly attributed to drummer Neil Peart, who accumulated a host of injuries and back issues over his 40-plus-year career with the band. But Lifeson, too, has long-suffered from arthritis in his hands and feet that made performing agonizing at times.

So fans might get an Alex Lifeson solo album eventually, but a tour to support that album might not be in the cards.
